Application nea May 27, 1922. serial No. 564.089. f

ject of the invention is to swing` the picker sticks thereof through the intervention of gears, that are partially turned with the swinging of the lay hatten ofthe loom for which the picker sticks arer provided. A third object is to provide adjustable means to turn said gears, so that their operations can be timed one with the other. @they objects will appear in the specifica-tion and claims. y

In the accompanying Vdrawings Fig. l represents a front elevation of a loom vwith the improved shuttle operating mechanism incorporated therewith l2 shows a top plan view of Fig'. l; Fig. Sindicatesan enlarged left hand lside view of Fig. l; Fig'.

4 shows an enlarged fragmentary port-ion of Fig. l; Fig. 5 is a top view of Fig. 4; Fir.A 6 shows a section of Fig. 4 on the line 6, 6; Fig. 7 indicates a section of'Fig. 3 on the line 7, 7 .j Fig. 8 represents an elevation of 4some details; Fig. 9 shows a right hand side view of Fig. 8 and Fig. l0 is a top view of Fig. 8.

The loom is indicated with the similar side frames A. A', which comprise each'the upper horizontal member 20. the lower hori.' zontal member 21` the front vertical member 22, therear vertical member 23 and the central vertical member 24. y

A *sleeve 35 is vformed at the bottom end of each arm andis fastened to the shaft 33. An angular shaped seat 36isformed at the topfend thereof. A' pair ofjournal ears 37 isoformed at the topl endl of'each of the arms B7 B. A lug` 38'is formed with each of the said arms. th'e'guide openings 43 is seatedoupon andl Journal brackets 44 are supported upon the members 2O of the frames A, A* and have journaled therein the usual crankshaft 45 [fastened to the seats 36 Aof the arms B, B. l

having` the wrist pins 46. Links 47 connect V the wrist pins 46 and the pins 48 that are fastened to the journal ears 37.' A vU-shaped frame 50 extends from the member 20 of the frame A. A journal bearing 51. "is supportedon the frame 50 and in turnsupports one end of the crank shaft 45. A clutch pulley 52 is fastened toy the said crank sha-ft and a hand wheel 53 isy also fastened thereto.

The lay batten C has connected thereto the usual similar shuttle boxes 1),.D for the shuttle 54. Each shuttle box comprises the rearwall 55 with its lower longitudinal portion fastened to the said lay batteri C.

'The wall 55 has anopening 56 in which is i pivoted the arm 57. by means of the'pivot 58. An angular Aguide plate 60 iis fastened to the lay batten C for the vshuttle boX.

A bracket plate 62 has one end thereofk fastened to eachof the arms B. B and their lugs 3S. A bracket 63 having' the iournal bearings 64 and 65' is fastened to the plate A spindle l6'? is ,jourf 62 and a iournal bracket'66 isk also fastened to said plate.

naled in the bearing 64an'l has fastened i thereon the bevel pinion 68. A squaredelnd 69 with the threaded shank 70 yis formed with the spindle 67.v A shaft is journaled inthe bearings 65 and 66 and has fastened thereto, the bevel vgear 7 which in this instance isdoublethe'` diameter of the bevel pinion 68 and meshes therewith; A sleeve 76 with the Contact armv 77 is a'diustably fastened to the upper end of the sha-ft 73. Pinions 78 are fastened lto the 'cra-nk shaft 45. each of the members 20; of the frame-s A A. A pivot SOe'Xtends from each ofthe brack-v Journal brackets 79 are supported on'y ion,, .and thereby swing: itsnaccompanying f picker stick.
